About 5 degrees warmer Monday as flow aloft backs from westerly to
southwesterly.  Upper trough in the northeast Pacific will rotate a
short wave trough through eastern Oregon Tuesday with a slight
chance of thunderstorms there and also in the central Idaho
mountains Tuesday afternoon.  Moderate southwesterly winds in

sitting off the British Columbia coast will slowly track its way
southeast during this time period. Southwest winds out ahead will
help keep temperatures slightly above normal, but by Thursday
temperatures are forecast to start dropping once more. Unsettled
pattern persists for the rest of the period, but models are trending
this low to stay farther north which will limit the showers and
afternoon thunderstorms to farther north than previously expected.
By Sunday another trough starts to make its way southward keeping
temperatures below normal and chances of showers and afternoon
